Well I talked to ironclad49er, and there isn't a bukkit port yet, so that's the issue most likely. I'd like to know how you got the client side working though. It's not working for me when I tried it.
BWIww: I made a guide for that: http://forums.technicpack.net/index.php/topic,4473.msg27275.html#msg27275
Edit: ironclad49er said he would look into the issue I'm having with adding dynamic elevators to the Tekkit client. Hopefully once he figures out what the issue is, I'll be able to help him with getting a Bukkit port made.
